'00-'08 Ford Focus Antenna Replacement

LINKS TO PARTS BELOW!!!Common failure on Focuses from '00-'08. How Common? This video is the FIRST time I replaced it. I just had to replace it AGAIN for the same reason. Universal antenna replacement kits at the parts stores ARE NOT COMPATIBLE. A screw goes through the banjo-style connector and into the antenna base on the roof, then the mast or "whip" screws onto that. Whatever you do, DON'T LOSE THAT SCREW!!!!'99-'02 Mercury Cougars have a similar setup.FordParts.com:Base: #18813Mast: #18A886 Amazon.com:
